PACKING VESSEL.

SPECIFICATION forming part of Letters PatentfNo. 636,339, dated November7, 1899-.

Application filed December 29, 1898. Serial No. 700,579. (No model.)

-To all whom it may concern.-

Be it known that LHEEBEET H. HULL,a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful Improvement in Packing Vessels, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

The invention relates particularly to cans adapted for containing andpreserving various kinds of food, paint, and the like.

The object of the invention is to provide such a can which can becheaply made, is neat in appearance, and is capable of being easilyopened. v

The invention pertains to the construction of a ycap to close one end ofthe can (the end to be opened) and to the combination of the same withthe can, as hereinafter described, and pointed out definitely in theclaims.

In the drawings, Figure 1 is an elevation,

' partly in section, of a can containing my invention. Fig. 2 is a view,partly in section, of one corner of a Inodied construction. Figs. 3 andet represent sectional views of the can and its cap and a die by meansof which the cap may be presseddown upon the can with the result ofcausing the edges of the can to are outward. Fig. 5 is a sectional viewof one corner of the can after the same has been opened by pulling onthe rippingwire. Fig. 6 is a bottom view, partly in horizontal section,of the cap.

Referring to the parts by letters, A represents a capcapable ofembracing and closing one end of the can B. This cap consists of a top aof suitable shape (which will commonly be circular) and an annularcylindrical flange whose lower edge a' is rolled inward and embracesaripping-Wire C. In this rolled lower edge are two notches a2 d3. Theripping-wire C crosses one of these notches a3, extends around the cap,and out through the other notch a2, the end outside the cover beingsulciently long to be conveniently taken hold of by a suitable key orother instrument, by which it may be forcibly pulled out and thecap-flange cut thereby. A drop of solder may be employed to seal each ofthese two notches. In sealing the notch a3 the solder also attaches thewire to the cap,whereby when the der during this operation.

free end of the wire is forcibly pulled upon the wire will not be pulledout, but will cut the cover loose. It will not commonly be necessary toseal these notches and fasten the wire to the cap, as described, by anindependent operation, because the cap is capable of being soldered tothe can by the kind of machines now commonly used for such purposes, andthese two notches may be filled with sol- The can which is preferablyused with this cap is shown in Fig. l. It has a short cylindrical neck bof less diameter than that of the body of the can and a trie less thanthe interior diameter of the rolled edge of the cap, whereby the cap maybe easily placed over this neck. The diameter of the body b of the canis substantially the same as the external diameter of the cap. Theformation of this neck leaves a shoulder b2, against which the lowerrolled edge of the cap impinges and to which it is soldered. Thisshoulder is preferably concave, thereby to more exactly conform to thelower edge of the cap. Then the shoulder is concave, as described, lesssolder will be used in fastening the cap to the can. This constructionis illustrated in Figsvl, 3, and 4. Fig. 2, however, shows the cap usedto close the end of acan which has no contracted neck.

An upwardly and outwardly beveled bead a4 is formed around the edge ofthe top of the cap by bending the metal. The diameter of this bead atits inner edge is less than the diameter of the end of the can. It is ofcourse not necessary that the cap shall have this beveled bead toperform the functions heretofore described; but the bead may serve afurther useful purpose. If, for example, the cap is presseddown upon thecan with sufficient force by a die, substantially as shown in Figs. 3and 4, the upper edge of the can will by reason of the beveled bead becaused to Hare outward, as shown in Fig. 4, so as to fit with more orless exactness inside the flange of the cap. When now by pulling on thewire C the lower edge of the cap has been cut loose from the can, asshown in Fig. 5, the cap fits the outwardly-flared end of the can,wherefore the cap becomes a more or less tight-iitting cover, which maybe taken 0E or replaced at will. When the can is used IOO to containpaint or some analogous substance, this is a valuable feature. Vhen,however, the can is used to contain something else, as fruit orvegetables, it is customary to use the entire contents of the can at onetime, and therefore this flaring of the upper end of the can has littlepractical value and need not be used.` In other words, the cap need nothave the bead a4, or if it does the cap need not be forced down upon thecan, so as to curve the top of the can outward, as described. The otherend of the can may be closed by a cap E, having a hole e. The can may befilled through this hole, which may be closed by a cap-plate G, solderedover the same. What is the bottom of the can while it is beinglled-namely, the end which is closed by the wired cap A-becomes the topof the can when the can is opened.

Having described my invention, I claim- 1. A cap for closing the end ofa packing vessel, which cap consists of an end plate and an annularflange whose lower edge is rolled inward and has two notches a2 a3, anda ripping-wire embraced by said rolled edge, which wire extends acrossone of said notches around the cap and out through the other notch,substantially as and for the purpose specified.

2. The combination of a can and a cap therefor which has an annularfiange fitting over the outside surface of the can, said flange havingits lower edge rolled inward and having two notches in said edge, and arippingwire embraced by said rolled edge which wire extends across oneof said notches around the cap and out through the other notch wherebythe same solder which holds the cap to the can may hold the end of theripping-wire within the cap so that a pull on the wire may cut the cap,substantially as and for the purpose specified.

3. In a packing vessel, the combination of a can having a neck ofsmaller diameter than the body and having the annular upwardlyconcaveshoulder b2, with a cap having an annular flange with an inwardly-rolledlower edge, which flange elnbraces'the neck of the can and its loweredge fits said concave shoulder and is soldered thereto, and arippingwire embraced by said rolled edge, one end of said wire beingextended out through a notch therein, substantially as and for thepurpose specified.

4. A cap consisting of a plate having at its edge an outwardly andupwardly beveled bead and an annular flange depending therefrom andhaving its lower edge rolled inward, and a ripping-wire embraced by saidrolled edge and extending out through a notch therein, combined with acan having a reduced neck which extends upward substantially parallelwith the sides of the can and when the cap is forced down onto the canbends the edge of said neck outward beneath the bevel of the cap,substantially as and for the purpose specified.

5. In a packing vessel, the combination of a can having a neck ofsmaller diameter than the body, said neck continuing substantiallyparallel with the body, with a cap having an annular flange with aninwardly-rolled lower edge the external diameter of said flange beingsubstantially that of the can and the length of the fiange beingsufficient for said rolled lower edge to fit against the shoulder formedby the neck with the body of thecan, there being within said rolledlower edge a ripping-wire one end of which is extended out beyond thecover, substantially as and for the purpose specified.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.

HERBERT H. HULL.
